Title: Wing cam for a pattern wheel circular knitting machine
IPC: D04B15/82
Filed: 1969-05-07
Abstract: 1,235,419. Knitting machines. SINGER CO. 7 May, 1969 [13 May, 1968], No. 23335/ 69. Heading D1C. A blade wing cam 78 is mounted on the end of a pivoted arm 70 so as to engage the butts and lower those needles which after having been raised by cam 36 are not further raised by a pattern wheel 26 and return those needles to welt height. Any needle which is inadvertently misplaced causes the blade cam, by engagement between the needle butt and the leading edge of the blade cam, to be deflected out of the path of the butt against the action of a spring 72 pressing on the pivoted arm 70. The upper part of the arm 70 also carries a cam portion 80 which when the arm 70 and the blade cam 78 are in their normal projected positions acts as a guard cam restricting the movement of those pattern wheel selected needles which having been raised to knitting height engage the stitch cam 48 and are drawn downwardly between the stitch cam surface and the upper surface of the cam 80. Consequently any tendency for the needles to ricochet of the stitch cam 48 when knitting at high speeds and miss taking yarn is prevented by the upper surface of the cam 80. The cam 80 is of less depth than the blade cam 78 and enable the arm 70 and the cams to pivot back into position after the butt of an incorrectly positioned needle has passed the blade wing cam 78.

Abstract: 679,554. Pressure exchangers. JENDRASSIK, G. Sept. 1, 1950 [Sept. 9, 1949], No. 23433/49. Class 8 (i) In a pressure exchanger in which scavenging is employed at least at the heat rejection stage and the direction of flow of the gas supplied to and withdrawn from the cells during a scavenging period is axial with respect to the ring of cells, or has a substantial axial component, each cell comprises structure which, in association with duct means leading the scavenging gas to and from the cells constrains the current of such gas to undergo reversal of flow within the cell. A cell rotor 2 is mounted for rotating in an outer casing 1 and comprises an inner cylinder 4 and an outer cylinder 3 connected by radial partitions 5 forming cells 6 ; the cells are open at one end and closed at the other except for apertures 8, for transfer gas flow, which apertures communicate with apertures 9 in an end plate 1a of the casing 1. At front and rear corresponding apertures 9 are connected by pipes 10. An end plate 1b of the casing 1 has a sector shaped opening 11 which is connected to a duct 13 for low pressure scavenging and a similar opening 12 connected to a duct 16 for high pressure scavenging. The duct 13 is divided into ducts 14, 15, for the exit of expanded gas and the entry of fresh gas respectively and the duct 16 is divided into ducts 17, 18, for the entry of hot gas and the exit of compressed gas respectively. Each cell 6 is divided by a partition 19 into radially inner passages 21 and outer passages 20 connected at the end opposite to the ducting. The passages 20, 21 diverge in the direction of flow of the gases and the partition is shaped to reduce losses in the bend; guide vanes 22 may also be provided. In a modification the cells are divided into three radially disposed passages and the ducts 13, 16, into three separate ducts. Gas may enter into the centre ducts and passages and flow out from the outer passages and ducts or vice versa. In a further modification the partitions 5 radially inward and outward of the partition 19 are suitably inclined in and away from the direction of rotation to secure shockless entry of the incoming gas. In a further modification two contra-rotating cells are separated by a stationary structure which replaces the transfer gas pipes 10 and in a still further modification two adjacent contra-rotating cells are provided, transfer gas flowing directly between the cells. Specifications 290,669, [Class 8 (i)], and 672,994, are referred to.

Title: Metalation of halogenated thiophenes
Filed: 1947-08-26
Abstract: A halothienylsodium of the formula <FORM:0641260/IV (b)/1> (where of X, Y and Z, one is halogen and the others are hydrogen, alkyl or halogen), is prepared by treatment of a halothiophene <FORM:0641260/IV (b)/2> with sodium in the presence of an ether having a carbon atom to oxygen atom ratio not greater than 4 to 1, and in an inert atmosphere.  The product may be sulphonated, halogenated, acylated, alkylated, hydrogenated, nitrated, and treated with carbon dioxide to give acids.  The reaction is preferably carried out in the presence of small quantities of mercury, e.g. 0.01 to 0.25 g. atoms per mol. of thiophene, which may be used in the form of sodium amalgam.  Exemplary of the many specified thiophene starting-materials are: 3-chloro-, 2 : 3 - dichloro -, and 2 : 3 : 4 - trichlorothiophene, and the corresponding bromine and iodine compounds, 2-chloro-3-bromothiophene, 2 : 4 - dichloro - 3 - bromothiophene, 2 - chloro-3 - iodo - 4 - bromothiophene, 2 - bromo - 3-iodo - and 2 - chloro - 3 - iodothiophene, 2-chloro - 3 - methyl and 4 - iodo - 3 - methylthiophene, 2 - ethyl - 4 - bromothiophene, 2 : 3 - dimethyl - 4 - chlorothiophene and 2-bromo - 3 - methyl - 4 - ethylthiophene.  Suitable ethers for use in the reaction are dimethyl, diethyl and methyl ethyl ethers, and the dimethyl ethers of ethylene and polyethylene glycols; diethyl ether is preferred. Sodium is preferably used in finely-divided form, e.g. sodium sand. Nitrogen or the vapour of the ether may be used to give the inert atmosphere.  The reaction temperature is between about -10 DEG  C. and 50 DEG  C., preferably 20-40 DEG  C., and pressure may be used. It is preferable to use between 200 and 1500 ml. of the ether per mol. of the thiophene. In the examples (1, 2, 5-9), 2-chlorothiophene is treated under various conditions in ether with sodium or sodium amalgam to give 5-chloro-2-thienylsodium, which is carboxylated to give 5-chloro-2-thiophenecarboxylic acid; (3) 2-bromothiophene is similarly treated to give 5-bromo-2-thienylsodium, carboxylated to 5-bromo-2-thiophenecarboxylic acid; and (4) 5-iodo-2-thienylsodium and 5-iodo-2-thiophenecarboxylic acid are similarly prepared.
